wow you ran to forecast prices for 2020 when we are still in 2018 that shows that we are desperate to pass years to see high price increases. But I am of the view that things will be very different next year, so I believe that next year the price will start to increase a lot and we do not have to run to 2020.
I say this once again, I am not a good trader, I am not asking everyone to believe in this analysis prediction, but I like to discuss bitcoin prices on this thread with all communities, I agree 2019 maybe the price of bitcoin will rise again mid-year, but I'm still careful at the beginning of next year, hopefully it doesn't touch the $ 4000 floor wallin my opinion the price of bitcoin will not run as easily as you say, indirectly you say the price of bitcoin in 2021 will go to the moon. oh I see 2021 is the year of bitcoin 
2021 is only part of the highest price, it does not mean that we have to buy it in 2021, if you really think it is good 2019 is the right time to buy and take it, that's all I know and thank you for your opinion, cheers
